Override an Element?

I get an error trying to override the checkbox filter elelment.

“Your builder capability doesn’t allow you to access these settings.”

class Filter_Checkbox_Nested extends \Bricks\Filter_Checkbox {
	public $name        = 'filter-checkbox-test';
	public $icon        = 'ti-check-box';
	public $filter_type = 'checkbox';

	public function get_label() {
		return esc_html__( 'Filter TESTAAAA', 'bricks' ) . ' - ' . esc_html__( 'Checkbox', 'bricks' );
	}


	public function render() {
		
						echo "aaaaaaaaaa";
	}
}

Any one know how to properly do this?
